Design Waves and Wave Spectra for Engineering Applications
Thirteen years of hourly wave data measured at two of the National Data Buoy Center's (NDBC) buoy stations, one located in the northeastern Pacific and the other located in the northwestern...
The Evolution of Breakwater Design
The purpose of this paper is to present a view of the evolution of both the rubble mound and vertical faced breakwaters from the earliest design through the Iribarren and Hudson era. Determining...
Optimization of Reservoir Releases to Control River Sedimentation Using Differential Dynamic Programming
A new methodology is developed to address sedimentation control in alluvial rivers downstream of reservoirs. An optimization model is posed as a discrete-time optimal control problem to...
Education and Research in Water and Environment: Collaboration Between Minority and Majority Institutions
In 1992, a consortium of minority institutions (WREMCON) was formed to match expanding interest in environment with student interest to solve environmental problems and help with the nation's...
Problems Faced by Faculty in Minority Institutions
The primary objective of this paper is to list some problems faced by faculty engaged in both research and instruction in Minority Institutions (MIs) and to suggest solutions to them....
Elmhurst Quarry Flood Control Project
Conversion of a limestone quarry into an off-line reservoir provides flood protection for a rapidly developing County in the suburbs of Chicago....
Using GIS to Develop 2-D Hydraulic Models
As communities along rivers and streams continue to develop, the demand for more accurate floodplain analysis and flood warning will also increase. Computer systems continue to develop...
Evaluating Sensitivity of Hydraulic Control Optimization Models
Sensitivity of hydraulic control optimization models to variation in gradient constraints is examined. Monte Carlo simulation is used in conjunction with repeated optimization runs to...
Joint Probability Distribution of Rainfall Intensity and Duration
Intensity-duration-frequency (IDF) curves are widely used for peak discharge estimation in designing hydraulic structures. Accurate interpolated and extrapolated intensity values are difficult...
Integration of Reliability, Uncertainty and Optimization in Hydraulics Systems: Classification of Problem Types
Design and operation of hydraulic systems can be an extremely complex task. Although not widely accepted the application of deterministic optimization techniques can provide guidance to...
Integration of Reliability, Uncertainty and Optimization in Hydraulics Systems: Structural Reliability
The focus of this paper is to provide an overview of analysis and optimal design of systems in which the system reliability is dependent upon the structure of the system (such as the layout...
Designing Optimal Reliable Multiquality Water Supply Systems
A methodology which integrates optimal design and reliability of a multiquality water supply system is presented and demonstrated. The system constructed is able to sustain prescribed...
Intelligent Decision Support System for Stage Discharge Analysis
A Decision Support System (DSS) for fitting stage-discharge (S-D) relations is being developed by the University of Manitoba, Facility for Intelligent Decision Support, for Environment...
Impacts of Natural and Manmade Changes on the San Luis Rey River Environment
Almost all rivers continually change their position and shape based on various geomorphic and hydraulic factors, caused by natural as well as manmade activities on the riverine environment....
Modeling Flow in Variably-Saturated Porous Media
An expression for effective hydraulic conductivity to solve groundwater flow problems is developed. Also, a refined Monte Carlo (MC) simulation procedure is proposed. The developed methodologies...
Considering Uncertainties in Water Resource Designs
Design of water resource systems often faces with various uncertainties. The nature of problems in essence are decision making under uncertainties. This paper offers an introduction to...
